I'll start by saying that they're all good vito. The third is my favourite. It is similar to the fourth, but it looks better with the flowers "flatter". It seems more natural.

They all seem a little dark though. I can see that that is what you intended from the last one with the bee. It is bright and yellow. The others are orange on my screen. Nothing wrong with them being dark, especially if that is what you intended. But the title is "Bright Yellow Flowers" :lol:
